Abstract
The utility model provides a sounder capable of mixing multi-channel surround sound into triple-channel surround sound, which is suitable for the field of the sounder. The sounder comprises a power-amplifier host machine, a left sound box and a right sound box. The utility model is characterized in that the sounder further comprises a postposition surround sound box; and the postposition surround sound box is connected with the power-amplifier host machine. In the utility model, one path of the postposition surround sound box is additionally arranged on the basis of the existing two-channel surround sounder so as to realize the more ideal multi-channel playing effect with the postposition surround channel effect; compared with the existing multi-channel sounder, the sounder in the utility model greatly simplifies connection method and reduces cost, so as to facilitate installation, use and the like, so that the sounder is more suitable for the fields such as a flat television surround sounder, a car surround sounder, a computer multimedia surround sounder and the like.
Description
Technical field
The utility model relates to the sound technique field, relates in particular to a kind of multitrack surround sound and contracts and blend together 3 sound channel surround sound sound equipments.
Background technology
Along with improving constantly of people's living standard, people require more and more higher to stereo set or the panel TV Play System that has an acoustic function; At small-sized 2.1 ambiophonic systems of present panel TV as shown in Figure 1, comprising: power amplifier main frame, left voice box, right voice box and subwoofer audio amplifier, left voice box, right voice box and subwoofer audio amplifier are connected with power amplifier is host machine wired respectively.Though 2.1 surround sounds can satisfy user's demand to a certain extent, but, 2 channel stereo or the virtual surround sound that grows up on 2 sound channel bases are compared with multichannel surround sound (as: 5.1 or 6.1 and 7.1 multichannel surround sound), and its effect does not reach the effect of multichannel surround sound far away.
Existing 5.1 or 6.1 and 7.1 multichannel surround sounds, as shown in Figure 2,5.1 in the surround sound, generally main amplifier is placed on the place ahead, considers the high-fidelity requirement of main sound box simultaneously, 3 groups of audio amplifiers (left, center, right) in main amplifier and the place ahead all pass through wired connection, surround speaker places the main amplifier back upper place, woofer adopts wired connection, its comparison difficulty that just seems of putting and connect up because volume is bigger.The multichannel surround sound have Fig. 2 as can be seen, though can be realized powerful surround sound as 5.1 surround sounds.But, its cost height, install loaded down with trivial detailsly, also there is certain drawback.
Summary of the invention
The purpose of this utility model is to provide a kind of multitrack surround sound to contract to blend together 3 sound channel surround sound sound equipments.
The utility model embodiment is achieved in that a kind of multitrack surround sound contracts and blendes together 3 sound channel surround sound sound equipments, comprising: power amplifier main frame, left voice box and right voice box, also comprise rearmounted surround speaker, and described rearmounted surround speaker links to each other with the power amplifier main frame.
Wherein, also comprise the subwoofer audio amplifier, described subwoofer audio amplifier links to each other with the power amplifier main frame.
Wherein, also be provided with wireless transmitter module in the described power amplifier main frame, be provided with wireless receiving module in the described rearmounted surround speaker, rearmounted surround speaker and power amplifier main frame are set up wireless connections.
Wherein, be provided with wireless receiving module in the described subwoofer audio amplifier, subwoofer audio amplifier and power amplifier main frame are set up wireless connections.
Wherein, described rearmounted surround speaker and power amplifier main frame are set up wired connection.
Wherein, described subwoofer audio amplifier and power amplifier main frame are set up wired connection.
Wherein, described left voice box and right voice box are set up wired connection with the power amplifier main frame respectively.
The utility model embodiment compared with prior art, beneficial effect is: the utility model is by on existing 2 sound channel surround sound bases, increase by one tunnel rearmounted surround speaker, can realize the more satisfactory multichannel result of broadcast of rearmounted surround channel effect, compare with existing multichannel audio (as: 5.1 or 6.1 and 7.1 multichannel surround sound), connected mode, simplify greatly on the cost, brought the facility of aspects such as installing and using, be more suitable in panel TV surround sound sound equipment, automobile surround sound sound equipment, in the fields such as computer multi-media surround sound sound equipment.
